- Four hard-contact relay outputs for supported AC or DC loads
- Zero off-state leakage for circuits sensitive to solid-state leakage current
- One shared common with published make, break, and continuous contact ratings
1746-OW4 is an Allen-Bradley four-point ac/dc relay output module for SLC 500 chassis.
The module uses electromechanical contacts to isolate controller logic from a common-powered group of AC or DC field loads.
Before installation or replacement, verify common voltage, contact duty, inrush, minimum load, switching frequency, suppression, wiring-arm terminals, and output-image assignment.
Availability, condition, price, and shipping time for 1746-OW4 are confirmed during quotation.

- Apply the make, break, and continuous ratings for the actual AC or DC load
- Include inrush and power factor when sizing contactor or solenoid circuits
- Keep total common and module current within the published limit
- Install load-appropriate suppression at inductive devices
- Avoid suppression arrangements that violate the required machine release time
- Separate relay load conductors from sensitive analog and communication wiring
- Treat all four output contacts as one common-powered group
- Do not mix supplies that cannot legally or electrically share the common
- Label the wiring arm so source voltage and circuit ownership remain clear
- AC contactor and relay-coil switching in compact SLC 500 panels
- DC solenoid and pilot-device control within the published contact ratings
- Mixed industrial relay-load applications that share one compatible common supply
